Question 58

Personal area network (PAN) is used to connect wireless headphones to a smartphone.

A personal area network (PAN) is specifically designed for connecting devices over a relatively short distance, typically within a range of a few meters, making it ideal for pairing wireless headphones with smartphones.

A) Local area network (LAN)

A local area network (LAN) connects computers and devices within a limited geographical area, such as a home or office. While LANs can support multiple devices, they are not specifically tailored for the short-range connections typically used by wireless headphones and smartphones.

B) Extended area network (EAN)

An extended area network (EAN) is not a commonly recognized term in networking. It may refer to an expansion of network capabilities beyond a local area, but it does not specifically address the short-range communication required for connecting wireless headphones to a smartphone.

C) Wide area network (WAN)

A wide area network (WAN) covers a large geographic area and is designed for long-distance communication. WANs are not suitable for the direct, short-range connections needed for linking wireless headphones to smartphones, which are more efficiently handled by personal area networks.

D) Personal area network (PAN)

A personal area network (PAN) is designed for connecting personal devices over short distances, typically within a range of about 10 meters. This makes it the most appropriate choice for linking wireless headphones to a smartphone, as it facilitates quick and efficient communication between the two devices.

Conclusion

The correct answer, personal area network (PAN), is specifically designed for short-range connectivity, making it ideal for connecting wireless headphones to smartphones. Other options, such as LAN, EAN, and WAN, either cover larger distances or are not applicable to the context of personal device connectivity. Thus, PAN stands out as the definitive choice for this scenario.
